Hello everyone,
We all know how difficult is to make rockets to fly to space. The most important is what fuel pair is chosen. Each has its own probs:
1. Oxygen-Kerosene : the most common, but requires a huge and expensive cryogenic infrastructure and Oxygen mini-plant near.
2. Hydrgen-Oxygen: same expensive cryogenic inftrastructure + huge issue with Hydrogen itself - it leaks thru almost everything as the atom is the smallest
3. Other storable propelats (Acids, Hydrazines etc): super-toxic, super unstable, require a huge safaty infrastructure and storage.
4. Solid propellants: safety first no smoking , and very poor possiblity to do something when it is started
But thinking about this, do you have any ideas about someting in-between. Is there any propllants that can be less expensive, less harmful for life? Of course, not to compomise a lot with achieving of good specific impulse
And how to make the overal cost of launch reduced as much as possible, using the modern technics, materials and engineering.
I think such discussion can be pretty interesting.
